Section 4: FIRST-AID MEASURES
Inhalation:
If inhaled: Call a poison center or doctor if you feel unwell.
Acute and delayed symptoms and effects: May cause respiratory irritation.
Signs/symptoms may include cough, sneezing, nasal discharge,
headache, hoarseness, and nose and throat pain. This product may
contain traces of Hydrogen sulphide which may accumulate in confined
spaces. Hydrogen sulphide may cause symptoms such as digestive upset
and loss of appetite, loss of sense of smell and pulmonary edema. At 5001000 ppm Hydrogen sulphide may cause respiratory paralysis, collapse
and death without rescue.
Eye Contact:
If in eyes: Rinse cautiously with water for at least 15 minutes. Remove
contact lenses, if present and easy to do. Continue rinsing. Call a poison
center or doctor if you feel unwell.
Acute and delayed symptoms and effects: May cause eye irritation.
Signs/symptoms may include redness, swelling, pain, tearing, and blurred
or hazy vision. This product may contain traces of Hydrogen sulphide
which may accumulate in confined spaces. Hydrogen sulphide may cause
eye irritation at 1-20 ppm and acute conjunctivitis at higher concentrations.
Above 50 ppm H2S, eye irritation may include symptoms of redness,
severe swelling, tearing, sensitivity to light and the appearance of 'Halos'
around lights.
Skin Contact:
If on skin: Wash with plenty of soap and water. If skin irritation occurs: Get
medical advice/attention. Take off contaminated clothing and wash it
before reuse.
Acute and delayed symptoms and effects: Causes skin irritation.
Signs/symptoms may include localized redness, swelling, and itching.
Ingestion:
If swallowed: Call a poison center or doctor/physician if you feel unwell. If
vomiting occurs naturally, have victim lean forward to reduce the risk of
aspiration. Do NOT induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person. If
breathing or the heart stops, trained personnel should immediately begin
artificial respiration (AR) or cardiopulmonary resuscitation (CPR)
respectively. Get medical attention immediately.
Acute and delayed symptoms and effects: May cause gastrointestinal
irritation. Signs/symptoms may include abdominal pain, stomach upset,
nausea, vomiting and diarrhea. Sulphur may be converted into Hydrogen
sulphide in the intestine.

atmospheres. Flammable solid in powder form. Avoid contact with hot exhaust pipes and spark
sources of ignition e.g. steel tracked vehicles. Does not meet criteria for classification as Class
4.1 Flammable Solids under IMOT/TDG Regulations. When heated, this material may evolve
toxic and flammable Hydrogen sulphide.
Sensitivity to Mechanical Impact:
Sensitivity to Static Discharge:
MEANS OF EXTINCTION
Suitable Extinguishing Media:
This material is not sensitive to mechanical impact.
This material is sensitive to static discharge at temperatures
at or above the flash point.
Small Fire: Dry chemical, CO2, water spray or regular foam.
Large Fire: Water spray, fog or regular foam. Move
containers from fire area if you can do it without risk.
Unsuitable Extinguishing Media:
Not available.
Products of Combustion:
Oxides of sulphur. Hydrogen sulphide.
Protection of Firefighters:
Fire may produce irritating, corrosive and/or toxic gases.
Runoff from fire control or dilution water may cause pollution.
Hydrogen sulphide is heavier than air and may collect in low
lying areas and confined spaces. Wear positive pressure selfcontained breathing apparatus (SCBA). Structural firefighters'
protective clothing will only provide limited protection.
Section 6: ACCIDENTAL RELEASE MEASURES
Emergency Procedures:
Keep unauthorized personnel away. Stay upwind. Keep out of low
areas. Ventilate closed spaces before entering. ELIMINATE all
ignition sources (no smoking, flares, sparks or flames in
immediate area).
Personal Precautions:
Do not touch or walk through spilled material. Use personal
protection recommended in Section 8. Don full-face, positive
pressure, self-contained breathing apparatus.
Environmental Precautions:
Keep out of drains, sewers, ditches, and waterways.
Methods for Containment:
Contain spill. Avoid dust creation. Reclaim material if possible.
Reaction with environment minimal if kept cool and dry. Do not
flush to sewer or allow to enter waterways.
Methods for Clean-Up:
Use explosion-proof equipment. Dust can be a fire or explosion
hazard. Sweep up and shovel into suitable containers for disposal.

Other Information:
See Section 13 for disposal considerations.
Section 7: HANDLING AND STORAGE
Handling:
Do not swallow. Do not breathe dust. Keep away from heat, sparks, open flames, and hot
surfaces. No smoking. Ground/bond container and receiving equipment. Use explosion-proof
electrical, ventilating, and lighting equipment. Avoid contact with skin and eyes. Handle and
open container with care. Protect from moisture. When using do not eat or drink. Wash hands
before eating, drinking, or smoking. See Section 8 for information on Personal Protective
Equipment. Protect equipment against wet elemental sulfur corrosion.
Storage:
Maintain adequate ventilation at all times. Head spaces in storage tanks may contain toxic
Hydrogen sulfide gas. Keep product cool and dry. Keep away from sources of ignition. Avoid
generation and accumulation of dust. Rotation of storage may minimize acidity build-up. Acid
build-up can also lead to corrosive attack on metals and concrete structural materials. Store
away from incompatible materials. See Section 10 for information on Incompatible Materials.
Keep out of the reach of children.

PERSONAL PROTECTIVE EQUIPMENT (PPE)
Eye/Face Protection:
Wear safety glasses. Indirect vented, dust-tight goggles are
required if dust is generated when handling this product. Use
equipment for eye protection that meets the standards
referenced by OSHA regulations in 29 CFR 1910.133 for
Personal Protective Equipment.
Hand Protection:
Wear protective gloves. Neoprene material is recommended.
If product is hot, thermally protective gloves are
recommended. Consult manufacturer specifications for
further information.
Skin and Body Protection:
Wear protective clothing. Flame resistant clothing that meets
the NFPA 2112 and CAN/CGSB 155.20 standards is
recommended in areas where material is stored or handled.
Respiratory Protection:
If engineering controls and ventilation are not sufficient to
control exposure to dust or sulfur dioxide to below the
allowable limits then an appropriate NIOSH/MSHA approved
air-purifying respirator with Acid Gas/P100 combination
cartridge/filter, or self-contained breathing apparatus must
be used. Supplied air breathing apparatus must be used
when oxygen concentrations are low, if airborne
concentrations exceed the limits of the air-purifying
respirators or where hydrogen sulfide is present or possibly
present in confined spaces at hazardous levels.
General Hygiene Considerations:
Handle according to established industrial hygiene and
safety practices.

Persistence /
Degradability:
Solid sulfur is biodegradable; microbiological reduction to hydrogen sulfide
or oxidation to acidic oxy-sulfur species is possible. Both of these products
can have environmental consequences. Reclamation of sulfur rich wastes
is preferred over solid waste disposal. Commercial sulfur waste reclaimers
are available. Disposal must be in a certified landfill site approved for the
use of elemental sulfur. Special simultaneous application of limestone
normally required.
